  9. DSS-13 What are the benefits of a DSS? DSS  Excel Access N-GAGE(AHP) • involvesinteractionbetween decision maker and IT system thatsupplements&enhances human decision making by increasing: • understandingof the problem/decision by examining intuition/judgment/experience of decision makers (spousechoice, accounting policy, terrorist activity, pipeline path) • management of complexity& lack of structure • sophisticationof processing capabilities • speedof access to & processing of information • for an organization, the enhancement of human decision making contributes to: • increasingflexibility&productivity(Dock:Sparks, DHS:WSJ) • decreasing costs(Jackpot : Celtics, Rx:CPOE)

  10. S-1 New Science of Management DecisionHerbertSimon (1960) Introduction • …this journey (into the decision making process) is going to lead…(to) a major revolution in the art or science of management and organization(observed in CIOcases)S.7.4 • …the computer and the new decision-makingtechniques associated with it are bringing momentous changeslike machinerybrought to manual jobs S.xi.1 Proquest • In 1960, described a terrainmap of decision making that provides a framework the discussion in new millennium S.7.5 DSS.2

  11. What types of decisions do you face? Types of Decisions DSS-3 StructuredUnstructured Recurring Non-recurring DM DIMENSIONS STRUCTURE Processing specific info. in specified way No precise way to get a right answer AI (DSS) FREQUENCY Programmed TPS & MIS CIO assessments (N-Gage) Stoneyfield Farm (Access) Celtics Analytics Slam Dunk repeatedly or periodically Non-programmed Spouse Choice (N-Site) Hiring Technical Managers … or University Faculty Accounting Policy Caspian Sea Pipeline Path Plant Layout Line Balancing infrequently

  12. S-2 Different Processes for Programmed vs Nonprogrammed Decisions Types of Decisions • My reason for making the distinction is that different techniques are used for handling the programmed and the nonprogrammed aspects of decision makingS.5.3

  17. N-GAGE PROCEDURES •  Select Criteria • Select next level (2) • Name & describe elements (alternatives) • OK • Name & describe other alternatives as previously  until finished level 2 • Select goal • Select arrow button to draw relationships • Draw arrows from the goal to each criterion in level 1 • When finished drawing arrows to define relationships at level 1, select a criterion • Draw arrows from the criterion in level 1 to each alternative in level 2 to be rated on that criterion • Repeat the process for each criterion • Go to kennedyonline.us • Select N-Gage • Run • Run • File • New • Enter file name & description • Next • Enter # of levels under the goal ( goal is level 0) • Next • Enter goal name & description • Done • Select Design tab • Select Criteria Select level 1 • Name & describe criterion • OK • Name & describe other criteria as previously  until finished level 1

  18. N-GAGE PROCEDURES • Select the Solution tab • The hierarch of criteria & alternatives appears with the weights derived from the PWC process on the arrows and an IR (inconsistency ratio) in each box • If the IR > 0.10 a “Revise IR!” statement appears in the box • To revise the inconsistent comparisons, select the compare tab • Then, double click on the box with the inconsistency message • Redo the comparison process as before  • When all the inconsistencies have been resolved, select the Goal and the select the Solution tab • Print the hierarchy (if the hierarchy does not print on a single page, use print screen -PrtSc – to copy and past into PowerPoint or Word) • Select the Compare tab • Double click the Goal (a pair-wise comparison – PWC – table appears)  Select the first row in the table • Compare (approach : avoidance) the criteria using the number line • Select the next row in the table • Repeat the comparison process • OK when the comparisons are finished in the last row of the table • Double click a criterion in level 1 (a pair-wise comparison table appears) • Select the first row in the table • Repeat the comparison process in the table just as previously  • Repeat the process for each criterion • Select the Goal when finished the comparison process for each criterion

  20. DAY 3 DECISION SUPPORT SYSTEMS

  21. DSS-6 What is a Decision Support System (DSS)? DSS • DSS is a flexibleand interactive IT system designed to support decision making when problem is complex/ unstructured • frequently includesAI models like N-GAGE(AHP) • must be flexible / interactive in response to /because of problems that are complex / unstructured • usually involves qualitative criteria • typically in design/ choice phases of decisions • Examples: • Excel – what-if analysis in flexible budgets • MSAccess –data mining tools like queries and reports • N-GAGE (Expert Choice) – employs AHPto evaluate complex judgmental problem DSS-7 ACCESS PROJECTS

  23. AnalyticHierarchyProcess DSS-7 DSS: AHP • is an AI that modelshow experts approach complex hierarchical decisions involving qualitative criteria • Analytic -decompose complex problems into components (criteria / alternatives) • Hierarchy-organize into meaningful structure • Process of pair-wise comparisonsinvolving trade-offsassigns weights to the criteria and preferences to the alternatives more natural to compare two things than numerous elements (Saaty 2000, 1990, 1977)

  25. DSS-8 Simple, Intuitive…Powerful DSS: AHP • AHP has been applied to many diverse decisions: • Strategic Planning for a Caspian Sea Pipeline Project 2012 • AHP-Delphi GDSS for Locating WheyProcessing Facility2008 • N-Site: An Anti-terrorist Distributed Consensus Building and Negotiation Support System across the WWW 2006 • Evaluating Characteristics of FinancialInformation2004, 1995 • TQI Benchmarking Tools for Evaluating TQMprograms 2003 • Translating Financial Phrases into NumericalProbabilities1997 • Consensus Ranking of TechnicalManagerCandidates 1996 (ProQuest)

  27. DSS-13 What are the benefits of a DSS? DSS • involvesinteractionbetween decision maker and IT system thatenhances & supplements human decision making by increasing: • understandingof the problem/decision by examining intuition/judgment/experience of decision makers • sophistication of processing capabilities • management ofcomplexity and lack of structure • speed of access to and processing of information • for an organization, the enhancement of human decision making contributes to: • increasing flexibility and productivity • decreasing costs

  29. DSS-22.a What are the benefits of a GDSS? GDSS • Achieves the benefits of a team approach to a decision by: • compressing time /space so individuals can interact • brainstorming to share ideas, facilitate consensus and achieve acceptance • perspectives from different organizational levels revealing required expertise in candidates (nursing directors, nurse managers, staff nurses) • explicit functional criteria are encouraged rather than implicit / inappropriate criteria such as sex, race, religion. Omega H.138.2

  30. DSS-22.b What are the benefits of a GDSS? GDSS • minimizes the problemsof group processes including: • groupthink in which different ideas are suppressed • conflict by keeping focus on problem not personalities • status differences that restrict participation (nursing directors, nurse managers, staff nurses) • sequential interaction in face-to-face meeting, Omega H.138.2
